The trends are calculated using a median of pairwise slopes algorithm. Black dots represent high confidence in the sign of the long-term trend in the box (if the
5th to 95th percentile slopes are of the same sign). Boxes which have a thick outline contain at least three stations. Area averaged annual time series of percentage changes and trend lines are shown below each map for one area in northern Europe (blue line, 5.6 to 16.9 °E and 56.2 to 66.2 °N) and one in south‑western Europe (red line, 350.6 to 1.9 °E and 36.2 to 43.7 °N).

Climate change will affect Europe's cities in different ways. To give an overall impression of the challenge for European cities to adapt to climate change, the European Environment Agency (EEA) has published a series of detailed interactive maps, allowing users to explore data from more than 500 cities across Europe.

Climate change is already having substantial and widespread impacts around the world, according to the latest report from the Intergovernmental Panel on Climate Change (IPCC). Drawing on a larger body of evidence than ever before, it highlights a wide range of risks in vital areas such as food supply, human health and economic development.

With its "Roadmap for moving to a competitive low-carbon economy in 2050" the European Commission is looking beyond these 2020 objectives and setting out a plan to meet the long-term target of reducing domestic emissions by 80 to 95% by mid-century as agreed by European Heads of State and governments. It shows how the sectors responsible for Europe's emissions - power generation, industry, transport, buildings and construction, as well as agriculture - can make the transition to a low-carbon economy over the coming decades.
